It doesn't quite match Heinlein's 'tumblebug', but it's getting there.

Looks pretty darn close to me. All it's missing is some streamlined fairings.

Well, it is close to that photograph, but the verbal description doesn't match very well.
Quote:
A tumblebug does not give a man dignity, since it is abut the size and shape of a kitchen stool, gyro-stabilized on a single wheel.

How it was controlled is not mentioned, other than it being easily controlled, but my impression was that it was done through shifting the center of gravity of the rider.
